S tatistical jargon is plagued with technicalities and intricate mathematical notation. Throughout my experience in the biomedical field, I’ve encountered two types of people: those who feel an absolute fascination with this abstract language, and those who flee in terror every time they see formulas with a handful of Greek letters (although their studies are based on results from these formulas).
I work mostly for physicians and biomedical researchers with long-forgotten knowledge about applied statistics, so I end up spending more time answering questions of an interpretative nature than doing analyses. This is a direct consequence of how cryptic statistics can become even in their simplest manifestations.
One of the most frequently asked questions comes also from one of the most popular and commonly used statistical tests in medicine: the Student’s t-test and the p-value.
